' This invention relates to an improvement in warp beams.

9 Some of the silk mills which have been in business for a number of years, are still using what are known as the old-fashioned warp beams, and where it is desired to modernize those it has been a very expensive practice if the old beams have to be entirely discarded and replaced with the new type of beams; and some of the new type of beams are also inefl'ective because of a bending of the stubshafts or indenting of the threaded sleeves carried by the wooden barrel, when a conventional set-screw is used.

' My invention has been developed to provide an inexpensive manner of modernizing the old-fashioned warp beams without discarding them and at a comparatively small cost, resulting in tremendous savings to the mills, and at the same time to develop a modern type of beam in which many defects will be cured. However, the invention is not limited to the modernizing ofold beams, but is equally applicable to the manufacture of new beams, wherein the features of my invention may be incorporated.

One of the features of-my invention relates to the manner of attaching the stub-shafts to the wooden barrel in order to permit ready removal of the stub-shafts in the event that they become bent as very often happens, and, in order that they may be strengthened or replaced, the stub-shafts are removably attached by means of pins or the like to the end portions of spiders or castings, which are securely welded er -otherwise fastened in the ends of the threaded sleeves. When the stub shafts become bent, it is easy to remove them merely by driving out the pins and then straightening the shafts, or replacing them by new ones. At the same time, the spider or casting has a drive connection directly with the end of the wooden barrel through small lugs formed on one end of the casting, which project into the end of the wooden barrel.

Another feature of my invention is the protecting of the threads of the sleeve from the end of the set-screw used to adjust each of the flanges, and which set-screw has here tofore enga ed a portion of the sleeve. After severa adjustments, the set-screw may be caused to engage the threads instead of the smooth places intended to be engaged thereby, which results in injury to the threads. I have provided a pressure-bar which may be threaded to mate with the threads on the sleeve, and disposed in a notch in the hub of the flange to be engaged by the adjusting-screw in order to prevent any in ury to the threads by the set-screw in tightening the flange in an adjusted posi- Still another feature of my invention is the provision of a counterbore on the inside of each flange to admit the end of warpingpaper under the beam flange, thus doing away with the buckling of the paper at the outside of the warp, and also making it unnecessary to carefully and accurately cut the edges of the paper used to surround the wooden barrel and sleeves thereon.

In the accompanying drawings:

The usual Wooden barrel 1 is provided with threaded sleeves 2 on the opposite ends thereof, each of which threaded sleeves is adapted to receive the hub 8 of a flange 4.

As shown in Fig. 4, the threaded sleeve 2 forms a continuation of the surface of the wooden barrel 1, and by reason of the threaded connection between the hub 3 and the sleeve 2, each flange 4 may be adjusted inwardly or outwardly on the threaded sleeve the threaded sleeves to decrease or increase the space between the flanges. A layer of beaming paper is usually wrapped around the barrel between the flanges in starting the warp, and in order to receive this paper and to permit it to extend under the flanges I have provided a counterbore 5 in the central opening of each of the flan es, so that the edges of the paper need not be exactly true, and also doing away with a buckling of the paper at the outside of the warp.

To securely fasten'each flange 4 in an adjusted position, the usual set-screw 6 is employed, threaded radially through the hub 3; but instead of directly engaging the surface of the barrel or the threaded sleeve 2,

I have provided a pressure-bar 7 disposed within a notch 8 in the hub 3, and interposed between the end of the set-screw 6 and the periphery of the threaded sleeve 2, the inner face of the pressure-bar? being threaded as at 9 (see Fig. 3) to mate with the threads of the sleeve 2. This prevents the set-screw from directly engaging the threads and distributes the pressure over a plurality of threads which thus prevents injury thereto. The provision of mating threads 9 on the inner face of the pressurebar permits the latter to turn in the threads of the sleeve when the flange is rotated for adjustment, thus holding the bar against displacement, but where the bar is of soft metal or the like, the threaded inner face may be omitted and the bar held in place by the set-screw or the hub.

As shown in Fig. 4, each end of the wooden barrel 1 terminates in spaced relation from the outer end of the sleeve 2, so that the latter projects over the end of the wooden barrel. In modernizing the old-fashioned warp beam, this is accomplished merely by sawing off the ends of the barrel and applying the im provements thereto. I have a spider or casting 10 fitted within the sleeve 2- and Welded thereto, as at 11 in Fig. 6, but this spider projects outwardly from the end of each of 2, and recelves one of the stems or stub-shafts 12 therein, which is held in place by a locking-pin 13 extending through the spider 10 and the stem 12 to removably secure the two together. This pin may be driven out when it is desired to remove the stem for straightening or replacement. r

The inner end of each of the spiders or castings 10 has a plurality of driving-lugs 14 formed thereon, and which project into the end of the wooden barrel 1, forming a driving connection therebetween.

I have shown the spider 10 generally in the shape of a cross, although this may be of any other desired shape for the purpose; but in the form shown the sides are designated 15, and each has a peripheral notch or groove 16 therein.

A friction-head 17 is fitted over the end of each of the castings or spiders 10, and its stem or stub-shaft 12, and, as shown in Fig. 2, has lugs 18 extending into diametrically opposite notches or grooves 16, forming a connection between the friction head 17 and its casting 10.

Bolts 19extend longitudinally through the wooden barrel 1, between arms 15 of the castings 10, and through the friction heads 17, having nuts 20 on the outer ends thereof for securely holding the friction-heads to the ends of the barrel and castings.

The warp beam is used in the usual way to receive the warp-threads which are wound thereon.

While I have shown the features of my invention as having particular shapes, neve1= theless the shapes of these parts may be varied or modified as found desirable, and I do not wish to be limited as to the particular shapes of the parts, although the forms shown have proved very satisfactory in use.
